A knowledge-based semantic framework for query expansion

Searching for relevant material that satisfies the information need of a user, within a large document collection is a critical activity for web search engines. Query Expansion techniques are widely used by search engines for the disambiguation of user’s information need and for improving the information retrieval (IR) performance. Knowledge-based, corpus-based and relevance feedback, are the main QE techniques, that employ different approaches for expanding the user query with synonyms of the search terms (word synonymy) in order to bring more relevant documents and for filtering documents that contain search terms but with a different meaning (also known as word polysemy problem) than the user intended. This work, surveys existing query expansion techniques, highlights their strengths and limitations and introduces a new method that combines the power of knowledge-based or corpus-based techniques with that of relevance feedback. Experimental evaluation on three information retrieval benchmark datasets shows that the application of knowledge or corpus-based query expansion techniques on the results of the relevance feedback step improves the information retrieval performance, with knowledge-based techniques providing significantly better results than their simple relevance feedback alternatives in all sets.

A framework for the successful implementation of food traceability systems in China

Implementation of food traceability systems in China faces many challenges due to the scale, diversity, and complexity of China's food supply chains. This study aims to identify critical success factors specific to the implementation of traceability systems in China. Twenty-seven critical success factors were identified in the literature. Interviews with managers at four food enterprises in a prestudy helped identify success criteria and five additional critical success factors. These critical success factors were tested through a survey of managers in 83 food companies. This study identifies six dimensions for critical success factors: laws, regulations, and standards; government support; consumer knowledge and support; effective management and communication; top management, company wide, and vendor support; and information and system quality.

Technology transfer revisited from the perspective of the knowledge-based economy

This contribution proposes a revised framework for understanding and analyzing the process of technology transfer in the perspective of the knowledge-based economy (KBE). The underlying hypothesis is that the context of the knowledge-based economy introduces a major shift in the way technology transfer is conceived. The traditional model of technology transfer was based on the vision of technology moving from one well-defined economic unit to another well-defined unit. We suggest that in the new perspective technology transfer is essentially considered as a specific knowledge-transfer process that depends on the ways firms and other institutions manage knowledge, in particular the co-evolution of their absorptive capabilities and their knowledge-transmission strategies. To support the theoretical analysis, we analyze the business case of Nortel Networks over the past 50 years.

中国转型经济背景下创业地区差异的决定因素研究

 研究我国地区创业差异的决定因素,解释为什么不同地区创业水平存在差异。采用面板数据模型对我国29个地区1996-2006年的数据样本进行了检验,发现人力资本、私人财富和失业是地区创业差异的重要决定因素,市场需求增长也是重要的影响因素,但它主要通过人口收入的变化对创业产生影响。同时,进一步对1996-2001和2002-2006两个阶段进行了检验,发现各因素对不同阶段地区创业的影响存在差异,收入变化和人力资本因素一直产生显著影响,而人口变化、产业结构变化、失业和私人财富因素对地区创业的影响存在逐渐增强过程,后一阶段才表现出显著影响。这篇文章的研究结果最终解释了创业地区差异的成因,对于深入理解我国地区创业的特征将很有帮助。

低碳经济背景下企业管理变革的思考

低碳经济是我国当今社会经济发展的必然要求。作为我国社会经济发展和节能减排的重要微观主体,企业必须遵循低碳经济发展模式,依据低碳经济理念实施管理变革,创建低碳管理体系。文章界定企业低碳管理的内涵及要素体系,认为低碳管理是指企业依据低碳理念,以效益和责任相统一为目标,以低碳技术为核心,降低企业能耗,实现资源高效利用和经济与环境双赢的管理模式,并采用比较研究的方法对比分析传统企业管理模式与低碳管理模式下企业文化、战略管理和企业职能管理的区别。     

Innovation policy in an open economy: A normative framework for strategic and tactical issues

In this paper we present a normative analysis of innovation policy grounded in traditional economic principles which responds to the Schumpeterian critique of previous efforts in the neoclassical vein. Focusing directly on specific policy issues we pursue our analysis in two main directions, investigating the role of government in developing an infrastructure for innovation, and the optimal design of support schemes for R&D projects.The analysis suggests that while the structural and developmental issues stressed by the Schumpeterian school are of fundamental importance, identification of disparities between social and private gains, the “market failure” approach, provides an invaluable tool for understanding and formulating innovation policy. Focusing our attention on such factors as economics of scale, the incidence of externalities, and the Supranormal profits offered by imperfectly competitive markets, it provides a rational and realistic basis for anticipating where and how government intervention on behalf of industrial innovation is likely to be most effective. We view our contribution as a step towards bridging the gap between the neoclassical mainstream of economic analysis and the practice of innovation policy.     

氢经济社会发展前瞻及我国的对策

能源是国家发展的重大战略问题．能源安全是国家安全的重要组成部分。在人类能源利用历史中．世界各国的能源结构大致经历了两次重大转变．一是从19世纪中叶前的以生物质燃料为主转变为19世纪末到20世纪初的以煤为主．二是从20世纪中叶以来石油天然气代替煤成为人类的主要能源。伴随人类主要能源形式的重大转变而形成的“煤经济”、“石油经济”．有力地促进了人类经济社会的大发展。然而，化石能源终究是要枯竭的．以当前最重要的石油资源为例，最新预测结果是储采比为40年。

Building tribal communities in the collaborative economy: an innovation framework

In recent years, there has been a groundswell of initiatives aimed at providing platforms to share resources among people. Collaborative consumption provides a model for a ‘sharing economy’ where the dominant logic of consumers is resource access rather than ownership. This study examines the nature and development of a variety of collaborative consumption businesses; in particular, we explore how start-up entrepreneurs see the problems of creating a tribal community among customers and users. Interviews were carried out with founders and co-founders of collaborative consumption ventures during 2014–15. The results suggest that these organisations face many common issues. We develop and apply a framework to understand some of these. We find that collaborative consumption entrepreneurs strive to build a tribal community by matching, in an innovative way, supply and demand. This is typically done by co-creating shared commonality, developing scalable electronic platforms, and building trust into platforms using social media to develop proxy social capital. Consequently, by using existing ecosystems of social media, tribal communities can be formed and scaled much more quickly than via traditional marketing approaches.     

经济萎缩背景下的公司治理与销售绩效

国内外学者对公司治理结构与公司绩效的关系做了大量的实证研究,但有关公司治理与产品销售绩效的关系研究非常少。文章以金融危机时期的上市信息技术企业为样本,将销售绩效视为一个包括销售利润率、销售增长率和销售费用率等指标的整体多维构念,研究了公司内部治理结构与整体销售绩效的关系。结果发现:与以往研究结论不同的是,董事长兼任总经理分别与整体销售绩效、销售利润率和销售增长率呈正向关系;大股东持股比率与销售费用率呈负向关系。这些结论在理论上揭示了在经济萎缩的背景下,市场能够对董事会与管理层之间的矛盾有自动调和作用,这为信息技术企业的治理机制建设有重要启示。

Self-organization of industrial clustering in a transition economy: A proposed framework and case study evidence from China

The evolution of the industrial cluster has long been a comparatively difficult problem due to its complexity and the differing particularities of individual clusters. Based on a study of two clusters, this paper draws some logic and ideas from complexity theory and develops a generic framework to explain cluster self-organization. We present the cluster as a complex adaptive system (CAS) that experiences self-organization through four critical features: landscape design, positive feedback, boundary constraints, and novel outcomes. We then use this framework to analyze two clusters from the ICT sector within China's transitional economy. Finally, the paper draws out a few implications for our understanding of cluster development processes. In particular, we stress the importance of both path-dependence (due to initial conditions) and the unpredictability of developmental paths (due to the uniqueness of each cluster).
